Does anyone know of some 1/2 ID quick connect hose fittings that seal themselves when you pull the hose out?
I found
this and
this but I'm not sure if that's it, really expensive too. $40.56 for the 4 fittings needed.
The Corsair external unit has some that look like this which is more like what I was thinking of. Cheaper and less industrial than the above probably.
